2.4. Sauna heater stones
Quality stones meet the following requirements:
- Sauna stones should withstand heat and heat variation caused by vaporisation of the water thrown on the stones.
- Stones should be rinsed before use in order to avoid odour and dust.
- Sauna stones should have an uneven surface to supply a larger surface for the water to evaporate from.
- Sauna stones should be large enough, measuring about 50–100 mm to allow good ventilation between the
stones. This extends the useful life of the heating elements.
- Sauna stones should be piled sparsely in order to enhance ventilation between the stones. Do not bend the
heating elements together or against the frame.
- Rearrange the stones regularly (at least once a year) and replace small and broken stones with new, larger
stones.
- Stones are piled so that they cover the heating elements. Do not, however, pile a large heap of stones on the
heating elements. For a sufficient amount of stones refer to Table 1 on page 8. Any small stones in the package
of stones must not be piled on the sauna heater.
- The warranty does not cover defects resulting from poor ventilation caused by small and tightly packed stones
- Ceramic rocks are not allowed. They may cause damage to the sauna heater that will not be covered by the war
ranty.
2.5. Electric heating toggle
The electric heating toggle applies to homes with an electric heating system.
Sauna heater has a connection (marked 55) for controlling the electric heating toggle. Connector 55 and the heat-
ing elements are simultaneously live (230V).
2.6. If the sauna heater will not heat up
If the sauna heater will not heat up, please check that:
- the power is on;
- the main fuses of the sauna heater are intact;
- is there any error messages on the control panel. In case of an error message on the control
panel, please refer to the control panel instructions.
THE PERSON INSTALLING THE SAUNA HEATER SHOULD LEAVE THESE INSTRUCTIONS AT THE
PREMISES FOR THE FUTURE USER.
